Cheat:
     Start the game by typing [WC Origin -k] instead of just [WC]. The
[Origin  -k] part is case sensitive so there must be a capital 'O' and
lower  case  'k'. This gives your ship permanently full shields and if
you  press  [ALT]+[DEL]  together this destroys the currently targeted
enemy ship. This also works if you have targeted the Concordia or your
wingmen so be careful. The cheat also works with Secret Missions.

Tip:
     On the last mission where you have to destroy the Fralthi and the
Starbase  hit your thrust and fly straight over the top of the Fralthi
ships   avoiding  them  completely.  Destroy  the  Starbase  and  then
autopilot  back to the Fralthi ships. If you get close enought to them
the  self-destruct  saving  you  the difficult task of destroying them
yourself.
